Description:

The 720/740 is a dual chamber loadlocked system. The right 720 side is for silicon etching with an oxide mask. The left 740 side is for aluminum etching with either a PR or oxide mask. Either chamber can accomodate up to 200mm wafers. Pieces can also be processed, using a fused silica carrier wafer for the right side and a sapphire wafer carrier wafer for the left side.

Capabilities:

Chlorine based gases: Cl2, BCl3. Fluorine based : SF6, CF4. Methane

Load locked sample introduction

Up to 8 inch wafer capability

Turbomolecular pumping
